Direct impedance eduction of acoustic liners in multimodal ducts with shear flows

Jinyue Yang, Thomas Humbert, Joachim Golliard, Gwénaël Gabard

Impedance eduction of acoustic liners with flow is usually performed under the assumption of a uniform mean flow and in the presence of an incident plane wave. However, recent studies have demonstrated that shear flow significantly influences the propagation of sound waves and their interaction…
